JDBC, Ibtais, Hibernate, SPRINGJDBC is we usually in the process of development of the use of more than a few of the persistence of technology, specific in the development process how to choose it. First of all, the characteristics of the first is JDBC, this is the Java language provided by the specification, the main is to define some interfaces and communicati

Haven't written about database application for a long time, here is a review of Java JDBC. 1. Using Java JDBC Operations database typically takes 6 steps: (1) Set up JDBC Bridge, load database drive; (2) Connect the database, obtain the connection object (use database con

Wait a minute So we have to use the Java transaction here, this time using the JDBC Connection database, so we use the JDBC transaction! First look at what a transaction is: all the operations on

interface can be used to understand the implementation of the database at the bottom, so as to facilitate switching between multiple databases.For example, you can use the Supportscorrelatedsubquenes method to see if the database underlying can take advantage of the associated subquery.or call the Supportsbatchupdates method to see if a batch update is supported.Most of the DatabaseMetaData are returned as ResultSet objects, which can be obtained by
